    Study Notes

    • An interpreter is a software program that translates and executes code line by line, allowing for debugging due to the halting at the first error.

    • A device driver is a crucial software component that acts as a bridge between hardware and the operating system. Its functions include: controlling various hardware devices, enabling OS access to hardware features, and operating in diverse environments (e.g., printers, video adapters, network cards, webcams, digital cameras, scanners).

    • Application software is designed to perform specific functions or provide entertainment beyond a computer's fundamental capabilities. Three main categories are: personal (Office suite, communications software), departmental (CRM, accounting packages), and enterprise systems (ERP, document management).

    • Open-source software (OSS) is software where the source code is available to the public with permissive licenses. It can be studied, modified, and distributed freely.

    • Networks are collections of two or more linked computers. The primary differences between Local Area Networks (LANs) and Wide Area Networks (WANs) are their geographical coverage: LANs span a small area, while WANs cover large areas.

    • Networks are classified by topology, protocols, and architecture. The three types of topology are: bus (all computers connected to a single cable), star (multiple devices connected to a central host), and ring (each device linked to two others, forming a circle).

    • Network protocols (sets of rules and procedures) determine how data is sent and received between devices, with features like error checking and transmission media (physical or wireless). Prominent examples include Ethernet (used for LANs) and TCP/IP (used on the Internet).

    • Networks are built using various architectures, such as client-server, peer-to-peer, and hybrid. The client-server architecture divides responsibilities between clients (requesting services) and servers (providing services).

    • Network media refers to the communication channels used to transfer data. Transmission media can be physical (e.g., cables) or wireless (e.g., radio waves).

    • Networks are categorized by their applications and services: file transfer, email, instant messaging, voice and video conferencing, and remote desktop access.

    • The Internet is a global computer network that connects millions of computers across the world. It uses the TCP/IP protocol suite to transfer data between devices.

    • Network security refers to the protection of data transmitted and stored over networks, with threats including viruses, malware, and unauthorized access. Common security measures include encryption, firewalls, and antivirus software.

    • Network performance can be affected by various factors such as bandwidth, latency, and the number of users. Improving network performance involves implementing network optimization techniques and troubleshooting issues.

    • Cloud computing is a model for delivering on-demand access to computing resources (e.g., storage, applications, and data) over the Internet using a pay-as-you-go pricing model.

    • Virtualization is a technology that allows multiple operating systems or applications to be run on a single physical machine by abstracting and sharing the hardware resources.

    • Network management involves monitoring, controlling, and maintaining the performance, security, and availability of computer networks. Common tools and techniques include network monitoring, configuration management, and incident handling.

    • An interpreter is a software program that translates and executes code line by line, allowing for debugging due to the halting at the first error.
